Shoe heel



April 17, 1951 J. B. SNIZEK SHOE HEEL Filed Sepb. 28, 1949 Patented Apr. 17, 1951 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to a, new and useful improvement in a shoe heel adapted for attaching to shoes, and particularly relates to that class of shoe heel which is made from a pair of setions.

One of which is permanently attached to the shoe and the other of which is detachably engaged by the sections.

It is an object of the present invention to provide a shoe heel of this class having an upper section and a lower section, the upper section beins secured to the shoe, and the lower seetion having a plurality of projections or bosses which engage in openings formed in the upper section for securing the two sections together.

It is another object of the invention to provide a heel embodying a pair of sections one of which has openings, the other having bosses and in which the bosses are slightly larger in diameter than the openings.

Another object of the invention is the provsion of a heel of this class having an upper section and a lower section, the lower section being secured to the upper section by bosses mounted thereon which project nto onenings formed in the upper section and in which the lower section has an inclined face engaeing the opposed face of the upper section which straightens out upon being mounted in position so as to provide a vacuum seal.

Another object of the invntion is the provision of a heel havine an upoer section and a lower section formed from rubber or the like and in which the lower section has its peripheral edge inclined to the plane of the heel proper so that when the two sections are mounted together, the peripheral edge of the lower section will align wi+h the neripheral edee of the upper section.

Other objects will appear herein.

Forminzz a part of this specification are drawings in which,

Fig. 1 is a side elevational view of a fragment of a shoe showing the invention attached, the invention beine shown in sections.

Fig. 2 is a, perspectve view of the upper section of the heel attached to a shoe,

Fig. 3 is a perspective view of the lower sectin of the heel,

Fig. 4 is a fragmentary sectional view showing the parts in separated relation with the upper part mounted on a fragment of a shoe.

In the drawings I have shown a fragment of a shoe 8 having the heel supporting portion 9 to which is secured a rubber upper section Ill of a heel. Formed in this section I 0 are spaced 2 apart openings II which are spaced inwardly from the perimeter of the heel section. The openings I2 are formed for recepton of securing means II and it will be noted that these openings I2 are positioned inwardly of the outer edge of the openings I I. The lower secton I3 of the heel is provided with the spaced apart projections or bosses I4 which are adapted to enter the openings II. As shown in Fig. 1 these bosses I4 are of less leneth than the thickness of the heel section ID so that there is a space in the opening II at the upper or inner end of the boss I4. As shown in Fig. 4, the diameter of the bosses I! is slightly larger than the diameter of the openings II and, the opposed face I 5 of the heel section I 3 adjacent to the bosses I 4 is inclined to the main plane of the heel section I 3. It will a so be noted that the perimeter I 6 of the heel section I3 is inclned to its plane.

When the upper section Ill is secured by the nail I'I to the heel supporting portion 9 of the shoe 8, the openings I I will be projected outwardly bevond the outer part of the nail. Consequently, a part of the heel and a part of the openings II in the heel section I0 are positoned outwardy bevond the nails so that a twistimz or bending of the edze of the heel surnoortine secton I0 will not disturb the nails I 1 and cause them to pull loose. After this upper section I I! has been fastened in positon, the lower section is mounted on the upper section bv forcine the resilient. yieldable bosses or projectons I4 nto the slightly smaller openings II. In this operation, these bosses are placed under strain and distorted out of their natural shape and size so that they form a sealine contact with the openinsr H. At the top of the opening there is a space in which a r is imnrisoned thus formina a cushion. Due to the fact that the members I4 tightly seal the openinzs I I. air cannot enter the. openinqs II and consequentlv, the removal of the section I 3 is prevented. The section I 3 aan however. be removd bv further distorting and lene hen ng the projections or bosses I4. Conseouently, these bosses must be fiexible and stretchable. As the inclined face I5 is brought nto ensaeement with the opposed face of the section II), this inclined face is straghtened out by shoving the bosses 01 projections I4 inwardly a sufiicient distance and by straightening out this inclined face, a tight seal between the opposed faces of the two sections I 0 and I3 is eiected so that air cannot enter between these sections thus further resisting any undue remo val of one section from the other. Experience has shown that t is necessary to form the perimeter I6 inclined as shown in Fg. 4, so that when the section [3 is mounted on the section HJ as shown in Fg. 1, this perimeter l6 w11 register wth the perimeter of the upper section II]. Wth ths inclined face not present, the perimeter of the lower section I3 would nc1ne nwardly from the perimeter of the upper section I.

A heel constructed and mounted in ths manner is one which has proven most efiioient in use. It is durable, easly and quckly attached and may be easily and quickly detached when the lower section 13 becomes worn.

What I claim is:

A heel constructon of the c1ass descrbed oom prsng an upper section and a lower section, sad upper section beng adapted for attachng to the shoe and having a pluraltyof spaced apart openings extendng around and postioned inwardly of the perimeter thereof; said openngs being of constant diameter from end to end; a. plurality of eylndrcal projectons extending outwardly in spaced relation to each other from one faoe of said lower section, and of slightly greater diameter than the openngs in said upper section and formed from yeldable, stretchable materia l and insertable into said openngs for securing sad lower section on said upper section, the face of said lower section opposng the face of said upper section being inclined around said projectons prior to entry of sad projeotons nto sad openings and, upon entry of sad projections into said openings, 1ying fiat in engagement with the face of said upper section, the perimeter of said lower section beng inclined outwardly and downwardly from ts upper fase prior to mounting on to sad upper section and adapted upon mountng on sad upper section to be distorted to be in algnment with the perimeter of sad upper sectionand said cylindrcal openings being longer than said projections whereby air cushion pockets are provided at the upper ends of the projectons.
